With the introduction of netif_set_xps_queue, XPS can be enabled
by the driver at initialization.
Update the documentation to reflect this, as otherwise users
may incorrectly believe that the feature is off by default.
Fixes: 537c00de1c9b ("net: Add functions netif_reset_xps_queue and netif_set_xps_queue")

Currently, the aspeed-sgpio driver exposes up to 80 GPIO lines,
corresponding to the 80 status bits available in hardware. Each of these
lines can be configured as either an input or an output.
However, each of these GPIOs is actually an input *and* an output; we
actually have 80 inputs plus 80 outputs.
This change expands the maximum number of GPIOs to 160; the lower half
of this range are the input-only GPIOs, the upper half are the outputs.
We fix the GPIO directions to correspond to this mapping.
This also fixes a bug when setting GPIOs - we were reading from the
input register, making it impossible to set more than one output GPIO.

The current binding for the RPi firmware uses the simple-bus compatible as
a fallback to benefit from its automatic probing of child nodes.
However, simple-bus also comes with some constraints, like having the ranges,
our case.
Let's switch to simple-mfd that provides the same probing logic without
those constraints.

There is a bug in the device tree binding for cznic,turris-omnia-leds
which causes make dt_binding_check to complain.
The reason is that the multi-led property binding's regular expression
does not contain the `@` character, while the example nodes do.
Fix this, and also adjust the maximum address to 'b' as there are 12
LEDs.

The patch partially reverts some of the UAPI bits of the buffer
cache management hints. Namely, the queue consistency (memory
coherency) user-space hint because, as it turned out, the kernel
implementation of this feature was misusing DMA_ATTR_NON_CONSISTENT.
The patch reverts both kernel and user space parts: removes the
DMA consistency attr functions, rolls back changes to v4l2_requestbuffers,
v4l2_create_buffers structures and corresponding UAPI functions
(plus compat32 layer) and cleans up the documentation.

Pull networking fixes from Jakub Kicinski:
- fix failure to add bond interfaces to a bridge, the offload-handling
code was too defensive there and recent refactoring unearthed that.
Users complained (Ido)
- fix unnecessarily reflecting ECN bits within TOS values / QoS marking
in TCP ACK and reset packets (Wei)
- fix a deadlock with bpf iterator. Hopefully we're in the clear on
this front now... (Yonghong)
- BPF fix for clobbering r2 in bpf_gen_ld_abs (Daniel)
- fix AQL on mt76 devices with FW rate control and add a couple of AQL
issues in mac80211 code (Felix)
- fix authentication issue with mwifiex (Maximilian)
- WiFi connectivity fix: revert IGTK support in ti/wlcore (Mauro)
- fix exception handling for multipath routes via same device (David
Ahern)
- revert back to a BH spin lock flavor for nsid_lock: there are paths
which do require the BH context protection (Taehee)
- fix interrupt / queue / NAPI handling in the lantiq driver (Hauke)
- fix ife module load deadlock (Cong)
- make an adjustment to netlink reply message type for code added in
this release (the sole change touching uAPI here) (Michal)
- a number of fixes for small NXP and Microchip switches (Vladimir)

future as I try to delegate more things to Jakub" ]

Tunnel offload info code uses ETHTOOL_MSG_TUNNEL_INFO_GET message type (cmd
field in genetlink header) for replies to tunnel info netlink request, i.e.
the same value as the request have. This is a problem because we are using
two separate enums for userspace to kernel and kernel to userspace message
types so that this ETHTOOL_MSG_TUNNEL_INFO_GET (28) collides with
ETHTOOL_MSG_CABLE_TEST_TDR_NTF which is what message type 28 means for
kernel to userspace messages.
As the tunnel info request reached mainline in 5.9 merge window, we should
still be able to fix the reply message type without breaking backward
compatibility.

Remove link to litmus tests that didn't make it to upstream. Fix ringbuf
benchmark link.
I wasn't able to test this with `make htmldocs`, unfortunately, because of
Sphinx dependencies. But bench_ringbufs.c path is certainly correct now.

- Opt us out of the DEBUG_VM_PGTABLE support for now as it's causing

- Fix a long standing bug in our DMA mask handling that was hidden

- Fix a boot failure on systems with large amounts of RAM, and no
hugepage support and using Radix MMU, only seen in the lab.
- A few other minor fixes.

This reverts commit 14775b04964264189caa4a0862eac05dab8c0502 as there
were still some parsing problems with it, and the follow-on patch for
it.
Let's revisit it later, just drop it for now.

arm64 requires a vcpu fd (KVM_HAS_DEVICE_ATTR vcpu ioctl) to probe
support for steal-time. However this is unnecessary, as only a KVM
fd is required, and it complicates userspace (userspace may prefer
delaying vcpu creation until after feature probing). Introduce a cap
that can be checked instead. While x86 can already probe steal-time
support with a kvm fd (KVM_GET_SUPPORTED_CPUID), we add the cap there
too for consistency.

While reviewing a separate patch, I noticed that the formatting of the
commands, variables, and arguments was not in a monospaced font like the
rest of the Kbuild documentation (see kbuild/kconfig.rst for an
example). This is due to a lack of "::" before indented command blocks
and single backticks instead of double backticks for inline formatting.
Add those so that the document looks nicer in an HTML format, while not
ruining the look in plain text.
As a result of this, we can remove the escaped backslashes in the last
code block and move them to single backslashes.

the "performance" policy (ie. scaling_governor set to "performance"),
to avoid situations in which the kernel appears to discard data
passed to it via the EPP sysfs attribute.
